Enables Claude and other LLMs to interact with Supabase databases and Edge Functions through a secure API for performing CRUD operations and invoking custom payloads without requiring integration code.
  1. Log in to Your Supabase Account

  2. Select Your Supabase Project

    • Click on the relevant project you want the MCP server to access.
  3. Retrieve Project Credentials

    • In the left sidebar, navigate to SettingsAPI.
    • Here, you will find the following required credentials:
      • SUPABASE_URL: This is the "Project URL" shown near the top of the API settings page.
      • SUPABASE_ANON_KEY: This is labeled "anon public" under the "Project API keys" section.
      • SUPABASE_SERVICE_ROLE_KEY: This is labeled "service_role" under the "Project API keys" section.
  4. (Optional) Set MCP API Key

    • You can generate any secret string to use as MCP_API_KEY. For example: "my_secret_key".
    • Save this somewhere safe, as you’ll need to enter it in the FastMCP connection interface.
  5. Fill the FastMCP Connection Interface

    • Click the "Install Now" button for the Supabase MCP integration.
    • In the FastMCP connection interface, enter the following values you collected:
      • SUPABASE_URL
      • SUPABASE_ANON_KEY
      • SUPABASE_SERVICE_ROLE_KEY
      • MCP_API_KEY (your chosen secret)
  6. Finish Setup

    • Save the configuration in FastMCP.

Your Supabase MCP should now be configured and ready to use!
